The species having pyramidal shape is: SO3, BrF3, SiO2, OSF2

OSF2 has sp3 hybridization. According to VSEPR theory, we can conclude that the shape of OSF2 is a trigonal pyramid. Sulphur has a non-bonding pair of electrons on top, three downward legs of the pyramid are bonded to oxygen with a double bond to each fluorine with a single bond. SO2 is sp2 hybridized with three bond pairs and is trigonal. BrF3 is sp3d hybridized with trigonal bipyramidal shape. SiO𕒶3 is sp2 hybridized with trigonal shape.
